1994 6.5 turbo diesel no power (solved)

[@dirtwasp09]

thank you for just telling us plainly, i truly am grateful for that! so many guys go on about nothing and never get to the point. i have watched so many videos and got nothing. thanks

[@purcali]

I have been chasing this issue for 3 years since the day I purchased my Suburban from a friend. He did the same for 2 years before he sold it to me. Adjusted the sensor and couldn't have been happier when I stomped the accelerator and my drive shaft exploded!!!! No kidding I was actually happy to see what she was capable of!!!!👍 Aside from the time spent finding a stronger drive shaft the whole job took 10 minutes and cost nothing. Thank You a thousand times!!!

[@purcali]

I originally paid 2 diesel mechanics who didn't fix my problem (one who claimed to specialize in 6.5's). Then installed injection pump with remote PDM, replaced all ground wires as many suggested, installed a boost gauge and tested my turbo, new injectors, checked fuel lines and replaced filter, replaced lift pump which was bad but did not help and basically enjoyed avoided the passing lane and made sure to not park in a sloped parking lot as back up on a slope was impossible. Thanks again.

@@purcali Hi. '00 6.5TD K3500 Dump, relocated PMD with no power and black smoke at high throttle here. Been going around and around with mechanic and I'm psyched to have just found this video. So pulling the injection pump is 3hrs and installing it is another 3. What's the specific adjustment to the timing, "a couple hundredths to the passenger side"? When that doesn't work- what, pull it all and do it again?

[@MichaelMaloney1]

So did you move the sensor to the left a little or alot ? I am trying to get an idea of the way and how much to move it. I have a 98 6.5

[@purcali]

@@MichaelMaloney1 about 3/4 to the left if I remember right.

[@duncankitson5500]

Thank you, going to try timing my injector pump tomorrow after an engine swap.

[@LunaLecheLucky]

please show a video on how to apply that wastegate !

[@Yo_ItzJT]

Thank God for you thank you so much worked and working well thank you God bless🎉❤❤

[@VinylToVideo]

Can you carefully and in long description explain the issues you were having? I am wanting to do this to my 6.5 but a lot of people, including those familiar with the 6.5 are telling me not to lol.

[@jorgekazachek6514]

on my suburban 6.5 i think i need change also that sensor! because I make a lot things and still the same no power!! when I pulled a caravan looks like a pulled a 50ton!!! damm I don't know how is the problem!! great vedeo and good explained cheers from Norway

[@09Youba]

Thank you for the video. I don't have power on my 93 but I think it is the glow plug relay. Then I have a problem with after running and I turn it off it won't start so I have to let the engine cool down for 4 hours. I have to look that up. I only have 152 thousands miles on it.

[@MichaelMaloney1]

Great tip thank you. So did you move it over to the left side ? Is that correct ?

[@bowtieboy4273]

Great video thank you for taking the time!

[@davecrowe4812]

I done injection pumps for 40 years, you don’t change optical sensors unless you have a test stand to test the pump

[@TexRangerx]

Can you clarify more with some more detail

[@generalmcgarity7551]

Thanks for that great info!

[@jonatanreisin3647]

Hi, excelent video, do you have the part number for the optical sensor?

[@dieselnation555]

How she running now? Doing alot of work on my truck plan on checking this out myself

[@otoniel780]

Thanks for this video I fix my problem my 1999 gmc 2500 6.5 don’t want to go over 1500 rpm on the free way juts go 45 miles and smoke I clean the fuel tank I change the United sending work better the last thing I change the PMD my truck work good

[@Karfix]

Great Job man!

[@chriscampbell4758]

Thank you makes lots of sense been trying to figure out what’s wrong with my truck every time I hit the gas my check engine light comes on and then turns off the second I let go of the throttle but I’m it’s gutless just rebuilt the whole engine painted it new had Saunders new gasket set that was only $800 and then to resurface the heads Lock the valves it’s a pain in the ass to try it but it’s worth it if it’s going to fix it thank you for your video

[@marvinfisher6388]

Not sure about the check engine light but adjusting the optical sensor definitely did the job!

[@steverasmussen7523]

Just saw this video cool! I wonder how many hours/ miles your had at that time , inknow its a 3 yr old video

[@bobbbaz2526]

Problem solving vids are great. Do you have any site/link or tips of how to roughly adjust it? Is it only throu odb scanning? Regards

[@marvinfisher6388]

I believe it's obd scanning but it's similar to old school timing just move it a little and try it. I didn't have all the tools for that but you definitely get results!

[@marvinfisher6388]

I just moved it a little but not a lot, did it the old school way but you get results fast!

[@ESLinsider]

I wonder if this is my problem. I got codes 216 & 1216.and lower power and random shut downs while driving

[@anthonyrybczynski5420]

Just make sure that you didn't bump the timing too far. It can be catastrophic.

[@cjdowndemocrats6746]

Good comment is this where all timing is done?

[@cjdowndemocrats6746]

How do we know if advanced or to retarded with timing lights like old days

[@anthonyrybczynski5420]

@@cjdowndemocrats6746 I just went by the manual and the scan tool pids. I watched a couple KZbin videos too. I work at a Ford dealership now so not seeing 6.5 issues anymore.

[@ESLinsider]

@@anthonyrybczynski5420 What manual?

[@anthonyrybczynski5420]

@@ESLinsider I actually watched a 6.5 diesel youtube channel where the guy posted regular videos doing 6.5 repairs in his backyard shop i think. I used prodemand for the spec to confirm. If you want it I can look it up and post a video tomorrow. I have access to online manuals at work. In my case I had no luck monitoring the scan tool pids with most newer scan tools they won't communicate with that old junk. I had luck with a snap on brick scan tool that's old as fuck. This scan tool was made in 1994 to 1998 old af. If you actually need the spec let me know. It's really easy to setup.

[@kansascitynutcompany2909]

After you did this did you have the service engine light on all of the time or other codes that don't go away that are stored and don't illuminate the SES?

[@marvinfisher6388]

The codes were on before I started and they were still on when I finished not sure what they were but it ran good so I didn't worry about it sorry I couldn't be of more help with that

[@alfredolobo8573]

Thank you 🙏 I will do that!!

[@aleksandrzhila8865]

I changed many sensors, nothing happens. Same get little better start. I'll try adjust optical will see what happens. Thanks man!

[@eliseoferrer1459]

Hello , I would like to know what is the name in this sensor?

[@marvinfisher6388]

Optic sensor

[@stephannorthwest201]

Mine slides side to side with the set screw tight do I need to replace the injection pump? 93 Chevy 3500 6.5

[@marvinfisher6388]

I would say there's something loose in your pump I don't remember mine moving like that

[@stephannorthwest201]

@@marvinfisher6388 thank you it definitely didn't feel correct that's for sure

[@cocainehernandez919]

We don’t have the same problem I’ve narrowed my no crank no start problem down to a bad optical sensor as I have disconnected it in order for the computer to take data from the crankshaft position sensor instead in order to start. I watched this video because I know it has to be adjusted correctly to run properly and I think I will just make a shim to make sure the new sensor gets installed in the same place.

[@eedom69]

Is that something you can do without taking the pump out or? Igot a code 0216 and trying to figure it out.

[@marvinfisher6388]

Sorry I don't follow this but yes just take off the Intake then the top cover on the pump...

[@gentilejoshsaved1646]

[@sqmptn]

Hows your truck running after a couple years? Where you going to replace the pump because the lack of power, or did it throw a code you were trying to resolve? also did the new sensor come with the replacement gasket or did you use a gasket maker/sealant? Thanks

[@marvinfisher6388]

I never changed the optical sensor just adjusted it, yes it had codes as before but runs good.. Never replaced the seal just used the old one..

Hey I have a 93 Chevy c3500 and I put a new fuel pump and filter and she still shuts off after running up the road but idling she will stay on for ever

[@Chanflez13]

Wilson Valentin Check your PMD! might need to relocate if it's in stock location

[@wilsonvalentin1738]

Someone told me it's not pmd I don't have one mines is mechanical

[@mellis338L]

Wilson Valentin your injection pump is bad plain and simple

[@nolanbrown84]

Wilson Valentin did you ever get your truck running properly? There are a ton of things to check before throwing a new injection pump at it.

[@repairdude7972]

my 95 2500 does the same thing, just shuts down while running down the road. never has died while at idle. pmd is new and relocated with heat sink,extra grounds have been added but still does it. it is like something trips a resettable circut in the computer cuz 15 seconds later it will fire up every time then it might not do it for 5 min or might wait 5 weeks till it does it. seems to be a never ending problem.

[@JamesDavis-rz2cq]

Awesome find man! I've actually had optic sensor codes and fuel shutoff solenoid codes intermittently. I wonder if this will help

[@marvinfisher6388]

I had a lot of codes to after doing this but it ran great

[@JamesDavis-rz2cq]

Oh no I haven't adjusted mine yet but she's pretty gutless still after a decent bit of work. Notice the fuel mileage change at all? (When you can resist stomping the throttle lol)

[@marvinfisher6388]

I would say the fuel mileage is better it sounds better as well for being in a 1-ton it is pretty amazing the difference I also installed the Marine injectors I purchased off eBay later

[@greenthumb6875]

We did that with HMMWV’s in Iraq, in order to go down the road. Helped immensely…. We were switching from pathetic 6.2 to the equivalent of pathetic 6.5. Should be a crime when another country gets our equipment and see what we fight with…. Afghanistan and Russia are two examples… Chevy should be prosecuted for what they designed for American troops. China could have done better….

[@marvinfisher6388]

Thanks for that comment,,yes it changes everything when it comes to power....👍

[@Subgunman]

Fully agree we get the shit of the equipment but let’s not forget that some pansy assed congressman or senator voted for the cheapest equipment possible to get the military through hard times and in the end the manufactures ream the government for the highest cost per unit delivered. Who’s making the money? Politicians with kickbacks? Manufacturers placing high dollar bids for equipment that is total trash?

How far do move it.? All the way till it stops??

Sorry for that.. I guess it's possible to move it to much.

[@jasons7202]

You do have to know how to time a diesel...... following advice like "just max out the timing" is just wrong. There are tools to set the timing. The truck in the video ran better because the timing was set retarded initially. If your truck is set properly and you advance it, you will have problems.

[@mellis338L]

That is a calibrated parameter if it was out of spec all you had to do was pull the pump and have it recalibrated properly. Your method is a guess and a shot in the dark not good for longevity of the pump or motor itself. Actually it’s pretty terrible advice

[@marvfisher]

Your right! It was a shot in the dark . Unfortunately there's a lot of "good" advice on the internet that didn't work, mine did work,doesn't mean it's right for everyone .

[@marvfisher]

@@generalmcgarity7551 sorry man there are many things that could be the problem I messed with mine for a week trying different things , you may have something else wrong mine is running good now I don't like Electronics just a lot of trouble make sure the wastegate in your turbo isn't stuck shut check grounds at the back of the engine also make sure the pump is not sucking air from a rusted fuel line or bad hose common problem on those things as well open the bleeder valve on the fuel filter check for air bubbles when ignition is on should be a steady stream of fuel No Air.
